Abstract

The Montane subregion is one of the most diverse subregions within the province ofAlberta. The ecological diversity of this subregion creates a landscape that consists of a mosaicof different vegetative communities. This diversity means that these lands are valued for amultitude of uses, including summer range for livestock, prime habitat for many species ofwildlife, productive watersheds, wood fibre production and recreation. Despite the importanceof many of the vegetation types in the Montane for livestock grazing, there is little informationavailable on how grazing influences the plant community. There is little information on forageproductivity, carrying capacity and the associated community types that develop throughsuccession or from disturbance including grazing. This lack of information makes it difficult todevelop management prescriptions. As a result "Carrying capacity guides" are being developedfor each natural and subregion in the province to provide a framework that would easily groupthe vegetative community types. It is hoped this classification system can be used by field staffto assess carrying capacity and evaluate range health on lands within each region.

This guide represents the analysis of 1292 plots described in the Montane subregion Thisguide also includes plots done in the Montane subregion of Banff and Jasper National Parks, 8new community types described in the Ya Ha Tinda area west of Sundre and 7 community typesdescribed in the Cypress Hills. The 1292 plots represent 141 community types. These types aresplit into:

A. Native grasslands (Banff and Jasper Mountain ecodistricts) 14 types

B. Native grasslands (Blairmore and Morley Foothills ecodistricts) 23 types

C. Disturbed grasslands (Blairmore and Morley Foothills ecodistricts) 15 types

D. Native shrublands 17 types

E. Conifer types 26 types

F. Mixedwood types 13 types

G. Deciduous types 16 types

H. Cutblocks 10 types

I. Cypress Hills ecodistrict 7 types

The dominant plant species, canopy cover, environmental conditions, response to grazing, forage production and carrying capacity are outlined for each type.

Introduction

The province of Alberta is covered by a broad spectrum of vegetation regions fromprairie in the South, to alpine vegetation in the mountains and dense forests in the Central andNorthern part of the province. These broad vegetation regions have been classified into 20subregions for the province (Strong and Thompson 1995). Each of the 20 subregions consists ofgroups of plant communities which are influenced by environmental conditions and humanimpacts. Intensive management of these regions requires the ability to recognize the vegetativecommunities that have similar productivities and respond to disturbance in the same way. Theincrease in use of Alberta's northern forests has recently stimulated efforts to develop detailedclassification systems. Some of these classification systems include "Field guide to Forestecosystems of West Central Alberta" (Corns and Annas 1986) and "Field Guide to Ecosites ofSouthwestern Alberta" (Archibald et al. 1996).

The vegetative communities in the province of Alberta are highly regarded by mostresource managers for their ability to provide a wide variety of benefits. They are a classicexample of multiple use land, providing summer range for livestock, prime habitat for manyspecies of wildlife, wood fibre, productive watersheds and recreational areas. Despite theimportance of these vegetation types for livestock grazing, there is little information available onhow grazing affects their production. Specifically, there is little data on the levels of utilizationwhich are detrimental to a plant communities health. There is also little information on forageproductivity, carrying capacity and associated community types that occurs with grazing. Traditionally, these community types have been rated at 5 ac/AUM or 60 ac/head/year, butrecent work has shown that productivity can vary significantly depending upon the ecologicalconditions of the site.

The purpose of this guide was to develop a framework that would easily group thevegetative community types in the Montane subregion of the province. The ultimate goal is aclassification system that can be used by the field staff to assess carrying capacity and evaluaterange health on lands within the region.

Climate of Montane subregion

The Montane subregion composes only 0.9 percent of the province and is found in anarea south of Chain Lakes to the Montana border, portions of the Bow and Athabasca rivervalleys and isolated areas near Ya Ha Tinda and Grande Cache (Map 1) (Strong and Leggat1992). The Montane is distinguished from the other subregions by the presence of Douglas-fir(Pseudotsuga menziesii), limber pine (Pinus flexilis) and lodgepole pine (Pinus contorta). Elevationally the Montane occurs below the Subalpine in the mountains and above the FoothillsFescue grass and Aspen parkland subregions in southern Alberta.

Yearly precipitation ranges 308 mm to 1279 mm with two precipitation peaks occurringin May-June and again in August-September (Strong 1992). Summer monthly temperaturesaverage 11.9oC and are 2oC warmer than the Subalpine and 2oC colder than the Foothills Fescuegrass subregions. The Montane has the warmest winter temperatures of any forested region in

Alberta because of chinook activity and reduced influence of Arctic air (Strong 1992).

Approach and Methods of Classification

Approach: Ecological classification hierarchy and terminology

The system of classification in this guide was initially based on the community typeapproach of Mueggler (1988). Mueggler’s system was chosen over the habitat type approach(Daubenmire 1952) or ecosystem association approach (Corns and Annas 1986) because it couldclassify plant communities irregardless of their successional status. However, as the philosophyof rangeland health and proper functioning condition of a site evolved, it became apparent(through data analysis) that there was a need to also organize the various plant communitiesbased on their response to disturbance (i.e. disturbance vs. natural succession) within an areaunder similar environmental influences.

It was determined that the ecosystem classification system developed by Corns andAnnas (1986) and Beckingham et al. (1996) could accommodate this additional requirement. Thus, the new system developed for rangelands is a combination of Mueggler (1988) andBeckingham et al. (1996). Consequently, this guide adopts a similar ecological unitclassification hierarchy (ecosite, ecosite phase, plant community). In an effort to first, link thehierarchical system with the historic rangeland system, and second, to create a provinciallystandardized rangeland approach, slightly different classification terminology was developed. The new terms ecological site and ecological site phase (replacing Beckingham et al.’s [1996]

Page 16: Range Plant Community Types and Carrying Capacity for the … · 2016-03-03 · i RANGE PLANT COMMUNITY TYPES AND CARRYING CAPACITY FOR THE MONTANE SUBREGION Sixth approximation (Please

ecosite and ecosite phase terms respectively), provide subtle distinction to recognize theblending of the old systems and still be recognizable to readers familiar with the originalterminology. See figure 1 for a flow chart of both classification and general presentation ofinformation.

Methods: Plant community classification

Sampling for this guide occurred within the Montane subregion . This guide outlines theclassification of 1292 plots described from 1991 to 2004 .

The procedure for inventory of plots followed the Range Survey Manual (1992) and usesthe MF5 form. A plot consisted of a 10 m x 10 m macroplot and ten randomly selected 1 m x 1m microplots to record the canopy cover of shrubs and ten nested 20 cm x 50 cm microplots torecord the canopy cover of forbs and grass. The data for each site was analyzed using themultivariate analysis techniques of classification and ordination. Classification is the assignmentof samples to classes or groups based on the similarity of species. A polythetic agglomerativeapproach was used to group the samples. This technique assigns each sample to a cluster whichhas a single measure. It then agglomerates these clusters into a hierarchy of larger and largerclusters until finally a single cluster contains all the samples (Gauch 1982). Cluster analysis wasperformed in SAS and Euclidean distance was used as the Cluster Distance Measure and Ward’smethod was used in the Group Linkage Method. The groupings generated in cluster analysiswere overlain on the site ordination to determine final groupings. Ordination was used to findrelationships among species, communities and environmental variables. Ordination reduces thedimensionality of the data to 1-3 most important axes to which environmental gradients can beassigned. The ordination technique used in the analysis of the data was DECORANA(Detrended Correspondence Analysis). DECORANA detrends and rescales the axes therebyreducing the arching and compression of axes problems associated with other ordinationtechniques (Reciprocal averaging, Principle Components Analysis). Once final groupings weredetermined on the ordination specific environmental variables can be assigned to the variationoutlined on the ordination axes.

Plant community type summaries were generated in SAS, by averaging plant speciescomposition, range in composition, and percent constancy of occurrence, among vegetationinventory plots which were part of a community type. Environmental data was subsequentlysorted into the same plant community groupings to create the plant community descriptionsoutlined in this guide. The number of sample plots on which the description was based is alsoprovided (e.g. n=16).

Range Management Concepts and Methods

Ecologically sustainable stocking rates

Ecologically sustainable stocking rates (ESSR) values are suggested for each plantcommunity. These values reflect the maximum number of livestock (e.g. hectares(ha)/animalunit month(AUM)) that can be supported by the plant community given inherent biophysicalconstraints and the ecological goal of sustainable health and proper functioning of the plantcommunity. When the ESSR is multiplied by the area (e.g. ha) of a plant community polygonthe result is termed carrying capacity (CC), and is expressed as AUMs. Often the CC must beadjusted for management factors (e.g. reduced livestock distribution), management goals (e.g.improve rangeland health, multiple use and values, etc.), drought conditions, and other naturalphenomena impacting the site (e.g. forage quality, fire, pests, etc.). This adjusted/reduced valueis the grazing capacity (GC). The GC values are not provided in the plant community guidebecause the necessary adjustments are determined by the rangeland resource manager. Suggested ESSR values were determined from a combination of clipping studies, long-term rangeland reference area data, estimated production, range health trends and historicalgrazing experience. In order to sustain ecological health and function of the plant community,the ESSR has been established by the resource manager and is based on the ecological, climaticand seasonal conditions for each community type. In determining ESSR the forage requirementsfor one Animal Unit (AU) has been set at 455 kg of dry matter per month. The remainingbiomass production (carry over), is allocated for the maintenance of ecological functions (e.g.nutrient cycling, viable diverse plant communities, hydrological function, and soil protection,etc.) and plant community services (forage production, habitat maintenance, etc.). Theallocation of biomass production in this manor is well established, and supported, by thescientific community and the amount required, varies with Natural Subregion (Holechek et al.1995).

Rangeland Health

Range health is determined by comparing the functioning of ecological processes on anarea (e.g. plant community polygon) of rangeland to a standard (i.e. RPC) described within anecological site description. An ecological site is similar to the concept of range site, but abroader list of characteristics are described. An ecological site is defined by the Task Group onUnity and Concepts (1995) as, “a distinctive kind of land with specific physical characteristicsthat differs from other kinds of land in its ability to produce a distinctive kind and amount ofvegetation”. This guide can be used to determine the appropriate reference range plantcommunity, within an ecological site, for a rangeland health assessment.

Rangeland health assessments are utilized to make a rapid determination of the ecologicalstatus of rangeland. We use range health terminology (healthy, healthy with problems, orunhealthy), to rank the ability of rangeland to perform certain ecological functions. These

Page 19: Range Plant Community Types and Carrying Capacity for the … · 2016-03-03 · i RANGE PLANT COMMUNITY TYPES AND CARRYING CAPACITY FOR THE MONTANE SUBREGION Sixth approximation (Please

functions include: net primary production, maintenance of soil/site stability, capture andbeneficial release of water, nutrient and energy cycling and plant species functional diversity. For a detailed description on how to assess rangeland health for various plant communitiesplease refer to “Rangeland Health Assessment for Grassland, Forest and Tame Pasture” (Adamset al. 2003). A general range health category (Healthy, Healthy with problems, Unhealthy) hasbeen added to each community type description, which can be used as a guide when doing rangehealth assessments.

Range management objectives tend to favor the later stages of plant succession (late-seral to potential natural community (PNC) or good to excellent range condition) (Adams et al.2003). Late seral plant communities tend to be superior in the efficient capture of solar energy,in cycling of organic matter and nutrients, in retaining moisture, in supporting wildlife habitatvalues and in providing the highest potential productivity for the site. In contrast, early seralstages represent plant communities with diminished ecological processes, which are less stableand more vulnerable to erosion and invasion by weeds and non-native species. They also havediminished resource values for livestock forage production, wildlife habitat and watershedprotection (Adams et al. 2003). Healthy rangelands perform important ecological functions andprovide a broader suite of goods and services. In most cases these late seral plant communitiesare used as reference range plant community (RPC), but sometimes management goals influencethe choice of RPC (e.g. a cut block to be maintained as untimbered rangeland).

How to use the guide

Decide what category the community type is in. If it is in the Native grass or Shrubcategories it will not have tree cover and be found on steep south facing slopes or moist lowlandareas adjacent to streams and rivers. The predominant species will be native grasses, willow andbog birch. The community types described in the native grass and shrub category can be splitinto the Banff and Jasper Mountain (includes Banff and Jasper National Parks and the Ya HaTinda) ecodistricts and the Blairmore and Morley Foothills (includes Porcupine Hills,Whaleback and Castle) ecodistricts. The Disturbed grassland community types will resemblethe native grassland community types, but will show signs of extensive grazing pressure. Thesecommunity types will be dominated by grazing resistant species Kentucky bluegrass, clover anddandelion. A couple of moderately grazed community types with a predominant native speciescover are also found in this category.

The Deciduous category will be plant communities dominated by deciduous tree speciesaspen and balsam poplar and the Conifer category will be plant communities dominated bysubalpine fir, Engelmann or white spruce, lodgepole pine, limber pine, black spruce, larch orDouglas fir tree species. The Mixedwood category will contain communities that will have atleast 50% of the total tree cover as conifer or deciduous. The Cutblock category contains thetypes that have had timber harvesting. Finally, new community types that were described in theCypress Hills are outlined in the Cypress Hills category of the guide.

In order to understand how the community types in this guide are related to the ecositesand ecosite phases outlined in “Ecosites of Southwestern Alberta” (Archibald et al. 1996), the

community types in this guide are arranged by ecological site and ecological site phase (Table1). Table 1 is a reproduction of Figure 17 in the Ecosites of Southwestern Alberta guide withthe community types in this guide highlighted in the reference range plant community type andgrazing succession categories (Table 1). For the most part the ecological sites and ecologicalsite phases are the same, particularly for the forested community types, but a number of newecological sites and ecological site phases had to be created for the grass and shrublandcommunity types (Table 1). The ecological sites included (aa)(subxeric/medium) bluebunchwheatgrass, (cc)(submesic/rich) rough fescue grassland, (g) meadow (subhygric/very rich), (h)horsetail (hygric/rich) and (ij) fen (subhydric/rich). The (g) meadow, (h) horsetail, and (ij) fenecosites are similar to the (e) meadow, (f) horsetail and (g) fen ecosites found in the guideEcosites of West-Central Alberta (Beckingham et al. 1996). The ecological site phases include(aa1) bluebunch wheatgrass, (aa2) big sagebrush, (b4) yellow mtn. avens, (b5) bearberrygrassland, (c5) grassland, (cc1) rough fescue grassland, (d4) white meadowsweet Aw, (d5)shrubland, (d6) grassland (e4) shrubland, (g1) shrubland, (g2) grassland, (h2) horsetail Sw, (h3)horsetail shrubland, (ij1) treed fen, (ij2) shrubby fen and (ij3) graminoid fen. The “Grazingsuccession” category (Table 1) outlines the successionl sequence the community type willundergo with increased grazing pressure. A number of grazed ecological site phases wereincluded here. These included: (aa1a) grazed grassland, (cc1a) grazed rough fescue, (d3a)cultivated Sw, (d4a) grazed Aw, (d5a) grazed shrubland, (e2a) grazed Aw, (f1a) grazed Pb, and(g1a) grazed shrubby meadow

aa Bluebunch wheatgrass (n=104)

GENERAL DESCRIPTION

This ecosite is located on steep, south and west facing slopesthroughout the Blairmore and Morley Foothills ecodistrictsand the Banff and Jasper Mountain ecodistricts. The soils arepoorly developed, nutrient poor and generally have xeric orsubxeric moisture regimes. The grassland communities of theBanff and Jasper Mountain ecodistricts are often dominatedby northern wheatgrass, junegrass, fringed sage, sheep fescueand upland sedge species. In contrast the Blairmore andMorley foothills ecodistricts are often dominated bybluebunch wheatgrass. Big sagebrush dominatedcommunities are also found in isolated areas in the SouthCastle in this ecosite.

SUCCESSIONAL RELATIONSHIPS

Due to the nature of the site grasslands often remain theclimax vegetation on these sites. On moister sites shrubssuch as saskatoon, snowberry and chokecherry, often invadethe site with succession to Douglas fir. Heavy grazingpressure on the grasslands can often lead to a degraded sitethat is dominated by fringed sage, sedge, and little clubmoss.However, on moister sites timothy and Kentucky bluegrasscan often invade into this ecosite

cc rough fescue grassland (n=430)

GENERAL DESCRIPTION

This ecosite is typical of south and west facing slopesand lower slope positions throughout the Montanesubregion from an elevation of 1300 m to 1900 m. This ecosite is usually dominated by grass speciesbecause of the dry site conditions and westerlywinds. The soils of this ecosite are dominated bydeep black chernozemic soils. A number of roughfescue dominated sites have not had the speciescomposition change in over 30 years of nodisturbance indicating the climax nature of thisecosite in the Montane subregion.

SUCCESSIONAL RELATIONSHIPS

Due to the nature of the site grasslands often remainthe climax vegetation on these sites. On moistersites shrubs and trees such as saskatoon, snowberry,chokecherry and aspen often invade the site withsuccession to Douglas fir and Lodgepole pine. Heavy grazing pressure on these grasslands can oftenlead to a degraded site that is dominated by Kentuckybluegrass, timothy and clover species. Many siteswithin this ecosite have been cultivated and aredominated by cereal crops and smooth brome.

g meadow (n=22)(taken from Ecosites ofWest-Central Alberta)

GENERAL DESCRIPTION

The meadow ecosite tends to be mesic tosubhygric and occurs on fluvial parent materialswhere flooding and/or high water tablesincrease soil water content and replenishnutrients. The soils on these sites tend to havethick Ah horizons and loamy textures.

SUCCESSIONAL RELATIONSHIPS

The meadow ecosite is successional stable. Disturbance regime, cold air drainage, andcompetition from a diverse cover of shrubs,forbs and grasses slow or inhibit theestablishment of trees. If trees becomeestablished, the rich, moist loamy soils areconducive to rapid growth.

h horsetail (n=12)(taken from Ecosites ofWest-Central Alberta)

GENERAL DESCRIPTION

The horsetail ecosite is wet and nutrient rich. These sites are commonly found on toe andlower slope positions with fluvial parentmaterials where flooding or seepageperiodically replenishes the substrate nutrientavailability. With wet soils gleysolic soils arecommon and organic matter tends toaccumulate. Mottles were within 25 cm of thesoil surface in over 80% of the sites. Horsetailscommonly form a blanket over the forest floor.

SUCCESSIONAL RELATIONSHIPS

Balsam poplar is a pioneer species on thisecosite. White spruce is the expected climaxspecies, however its establishment may be slowdue to high vegetation cover.

ij fen (n=40)(taken from Ecosites of West-Central Alberta)

GENERAL DESCRIPTION

The rich and poor fen are combined in this ecosite.The fen ecosite is generally characterized by flowingoxygenated water and alkaline, nutrient-richconditions. This ecosite occupies level, depressionaland lower slope positions where impeded drainage orhigh water tables enhance the accumulation oforganic matter consisting of sedges, golden moss,tufted moss, and brown moss. Black spruce, whitespruce, and/or tamarack dominate the sparse canopyon the treed phase. Dwarf birch or willow form thecanopy of the shrubby phase and sedges dominate thegraminoid phase of this ecosite.

SUCCESSIONAL RELATIONSHIPS

Black spruce or white spruce are the edaphic climaxtrees on this ecosite. On calcareous materials blackspruce may be replaced by white spruce as the climaxtree species. Species composition and direction ofsuccession changes with changing hydrologic regime.As with other wetlands, fens have slow successionalrates so recovery from disturbance may also be slow.

Much of the variationis the result of complex topography, while the small size of individual ecosystems results in astrong ecotonal effect from the surrounding environments (Strong 1992). Much of the grasslandvegetation occurs on south and west facing slopes where seasonally low rainfall coupled withhigh evapotranspiration, dries the soil sufficiently to kill tree seedlings (Daubenmire 1978). Fireis also an important factor in determining the composition of grasslands because of the highflammability of the vegetation during the dry periods. A lack of fire and an increase in annualprecipitation favours the growth of trees onto the more mesic sites.

The Whaleback ridge, Porcupine Hills and south into the Castle area are composed of amixture of rough fescue grassland, aspen, Douglas fir and lodgepole pine. This area ischaracteristic of the Blairmore and Morley Foothills ecodistricts (Strong and Thompson 1995) anarea of ridged and rolling hills, with moderate slopes (6-30%) and Black Chernozemic soils onsubmesic to mesic sites. In the Banff and Jasper river valleys and northern Montane areas(Grande Cache, Red Deer river valley) open Douglas fir, lodgepole pine and Fringedsage/Junegrass communities are common on steep south facing slopes, shallow rocky soils andcoarse textured outwash (Strong 1992). These areas are typical of the Banff and JasperMountain ecodistricts. These ecodistricts have steep slopes (10-45%) and are dominated byEutric Brunisolic soils, with submesic to xeric moisture regimes (Strong 1992).

The Cypress Hills ecodistrict is an unglaciated plateau ranging in elevation from about1300 m in the east to1465 m at the highest point. Once considered boreal foothills, the area hasbeen reclassified as montane given the bimodal summer precipitation peaks (June andSeptember), the potential for freezing temperatures in all months and the combination of closed-canopied lodgepole pine forest with fescue grassland (Strong and Leggatt 1992). Soil parentmaterials are somewhat unique on the plateau where ancient tertiary gravels are exposed, or, maybe capped by a variable veneer of loess; fine silty material deposited by wind from post glaciallake beds to the west of the plateau. Soils are mostly Black Chernozems where grasslandvegetation has dominated. Thelma soils are loamy Orthic Black Chernozems associated withrough fescue communities on the top of the bench. Also associated with rough fescue cover,Delmas and Marmaduke soil series are gravel and shallow to gravel Orthic Dark BrownChernozems found on the shoulder of the escarpment. Orthic Dark Grey Luvisols, like the soilsseries Reesor (loamy) have developed where lodgepole pine or aspen forest have prevailed(Greenlee 1981). The grassland community types of the Montane subregion are outlined in Table2.

Banff and Jasper Mountain ecodistricts

The two dominant grassland communities in Banff and Jasper National Park include theFringed sage/Junegrass and Northern wheatgrass-Sheep fescue community types. Thesecommunities are typical of steep, south and westerly facing slopes with xeric to subxericmoisture regimes. The soils are poorly developed and nutrient poor. Variants of thesecommunity types included the Pussy toes/Junegrass community, which is also found on shallow,

1 Throughout the guide the rough fescue species listed for the Banff and Jasperecodistricts is likely a mixture of foothills rough fescue (Festuca campestris) and northern roughfescue (Festuca altaica), whereas the rough fescue listed for the Blairmore and Morley Foothillsecodistricts is Foothills rough fescue only (F. campestris). The rough fescue listed in theCypress Hills is a mixture of foothills rough fescue (F. campestris) and plains rough fescue (F.hallii) (Hill et al. 1995).

south facing slopes and the Juniper/Northern wheatgrass community which is typical ofregosolic, eolian sand dunes of the Athabasca river valley near Jasper (Corns and Achuff 1982). A Little clubmoss/Richardson needlgrass community was also found on shallow south facingslopes in small isolated areas within the fir, white spruce, lodgepole pine and douglas fir forests.

A Kentucky bluegrass-Junegrass/Dandelion community type was described on lower tolevel slope positions with submesic to subxeric moisture regimes. The presence of a high coverof Junegrass indicates the close affinity this grassland has with the Fringed sage/Junegrasscommunity type. The high cover of Kentucky bluegrass is indicative of heavy grazing influenceon this community type.

There were two upland shrub communities found on steep south facing slopes(Bearberry/Juniper and Rose-Snowberry). These community types represented the transitionfrom grassland to forest. The Bearberry/Juniper community type represents the transition fromthe grassland communities to the dry lodgepole pine, douglas fir and spruce forests. In contrastthe Rose-Snowberry shrubland appears to represent the transition to moister deciduous andspruce forests.

The grasslands in the Ya Ha Tinda area of the Banff and Jasper ecodistricts aretransitional between the grasslands described in Banff and Jasper National Parks and thegrasslands in the Morley and Blairmore Foothills ecodistricts of southern Alberta. Roughfescue1 is common in the Ya Ha Tinda which gives these grasslands some affinity to the roughfescue dominated grasslands in Southern Alberta. The predominance of junegrass and northernwheatgrass in the Ya Ha Tinda also gives these grasslands some affinity to the grasslandsdescribed near Banff and Jasper. The grasslands of the Ya Ha Tinda tend to be dry and welldrained. They occur on south and west facing slopes and coarse textured fluvial areas. The dryslopes tend to have a predominance of rough fescue, sedge and junegrass. In contrast the levelfluvial areas have a predominance of rough fescue and fringed brome. There are a number ofcommunity types in the Ya Ha Tinda that are transitional to the Upper Foothills and Subalpinesubregions. These include the Tufted hairgrass-Sedge and Bog birch/Sedge-Rough fescuedominated community types.

Blairmore and Morley Foothills ecodistricts

The dominant grassland community types of these ecodistricts near the Porcupine hillsand south into the Castle area are outlined in Figures 1 and 2. The Rough fescue-Idaho fescue-Parry oatgrass dominates mesic to submesic, lower slope positions and terraces with BlackChernozemic soils. Situated upslope from this plant community on slightly drier sites withpoorer soils, Parry oatgrass and Idaho fescue replace rough fescue as the dominant grass to form

the Idaho fescue-Parry oatgrass-Rough fescue community type. The Bluebunch wheatgrass-Sedge community is found on steep south-facing slopes with Regosolic and Brunisolic soils. Further upslope on dry sandstone outcrops and xeric hillcrests, limber pine dominatedcommunity types are very common. A Rough fescue-Sedge/Bearberry-dominated communitytype is found on hilltops throughout the area. This type tends to be drier than the lower slopedominated rough fescue community type, but it is moister and not as rapidly drained as theBluebunch wheatgrass-Sedge and limber pine dominated community types. Douglas firinvasion is common on these hilltop community types, to form the Douglas fir/Idaho fescue-Rough fescue and Douglas fir/Idaho fescue-Sandberg bluegrass community types. At higherelevations the ecotone between forest and grassland is dominated by the Snowberry-Rose-Saskatoon/Bearberry community type on drier sites and by the Pinegrass-Hairy wildryecommunity on moister sites with northerly aspects.

A Big sagebrush/Bluebunch wheatgrass-Sedge community type was described on agravelly south facing slope south of Blairmore. This community type is rare in Alberta andappears to be an extension of the Palouse prairie from Eastern Washington (Moss 1947).

There are a number of community types that are characteristic of moist, poorly drained,nutrient rich sites. These include Thimbleberry brush, Sedge meadows, Tufted hairgrass-Balticrush and Forb meadows. The Tufted hairgrass-Baltic rush community has plant species that aremore characteristic of the Subalpine subregion (Willoughby 1999) and may represent thetransition to the subalpine. Thompson and Hansen (2002) have described a number of graminoidwetland dominated communities. These types have been included in this guide. These typesinclude Water, Beaked and Awned sedge, creeping spike rush, bulrush and cattail dominatedmeadows. These community types are not common in the higher elevations of the Montane andare generally found in the eastern part of the Montane and are transitional to the Foothills Fescueand Foothills Parkland subregions.

There are a number of different grassland community types that have been influenced bygrazing pressure. Increased grazing pressure on a rough fescue dominated community type leadsto a decline in rough fescue and an increase in Parry oatgrass and Idaho fescue to form the Idahofescue-Parry oatgrass-Sedge community (Willoughby 1992). Continued heavy grazing pressureallows Kentucky or Canada bluegrass to establish to form the Kentucky bluegrass-Rough fescueor Canada bluegrass-Rough fescue community types. Continued heavy grazing pressureeventually leads to a decline in all native species and the site is dominated by Kentuckybluegrass and dandelion to form the Kentucky bluegrass\Dandelion community type. There are anumber of community types that have been seeded to tame forage species through cultivation orreclamation. These include the Smooth brome-Kentucky bluegrass and Creeping redfescue/Dandelion-Clover community types. On the drier slopes increased grazing pressure on the Idaho fescue-Parry oatgrass-Roughfescue and Bluebunch wheatgrass community types leads to an increase in low growing forbsand graminoids to form the Sedge/Little clubmoss-Moss phlox community type. On moistersites in these community types, grazing disturbance also leads to the formation of Parry oatgrass-Timothy and Northern wheatgrass-Kentucky bluegrass dominated community types.

Plant communities described in the Cypress Hills are associated with the nearly levelplateau or the upper edges of the steep escarpment or rolling uplands. They include a mixture ofrough fescue grassland and closed canopy aspen and lodgepole pine dominated forests. TheRough fescue (Festuca campestris Rydb.) related plant communities of the Cypress Hills Plateauare unique in the relatively high canopy of Shrubby Cinquefoil (compared to fescue communitiesdescribed in southwestern Alberta and appears to be a function of the gravelly soil) and theabundance of Intermediate oat grass, a major subdominant grassland species (Moss 1955). Onthe steep, dry slopes Western Porcupine grass often replaces Intermediate oatgrass in thesegrassland communities. Idaho fescue also replaces Intermediate oatgrass on shallower soils withgentler slopes. An unresolved issue is the apparent expression of Rough fescue as the FoothillsRough fescue (F. campestris Rydb.) bunch grass type on the top of the plateau and the PlainsRough fescue (F. hallii Vassey) rhizomatous form on the adjoining slopes of the Cypress Hills.

A1. Fringed sage/Junegrass(Artemisia frigida/Koelera macrantha)

n=11 This community type is typical of steep south facing slopes, at lower elevations in the river valleys nearBanff and Jasper. It is similar to the Junegrass-Plains reedgrass community described by Stringer (1973) near Banffand Jasper, the Purple reedgrass/Fringed sage community described by Bailey et al. (1992) in the Yukon and theFringed sage/Slender wheatgrass community described by Pojar (1982) in Northern British Columbia. Theprominent species of these grasslands (junegrass, northern wheatgrass, fringed sage, pussy toes and bearberry) aretypical of xerophytic and Mixed Prairie type grasslands throughout Western Canada. The dessicating winds of thearea and steep south- facing slopes would contribute to a climate that is similar to the Mixed Prairie subregion(Strong 1992). Grazing has also seemed to have had an influence on this community type. Stringer (1973) felt thatwith protection from heavy wildlife grazing Plains reedgrass and northern wheatgrass would increase and fringedsage and junegrass would decrease. Bailey et al. (1992), found that fringed sage, pussy toes, bearberry and lowgrowing sedges increased and purple reedgrass declined with increased grazing pressure on the Purplereedgrass/Fringed sage community type. It would appear the dry climate, and heavy grazing pressure by wildungulates have contributed to the development of this grassland community.

A2. Northern wheatgrass-Sheep fescue(Agropyron dasystachyum-Festuca saximontana)

n=5 This community type is similar to the Fringed sage/Junegrass community type. It occupies dry, steep,south facing slopes at slightly higher elevations than the Fringed sage/Junegrass community in the river valleys nearBanff and Jasper. This community type appears to be in better range condition than the Fringed sage/Junegrasscommunity type. As Stringer (1973) found, when the Fringed sage/Junegrass type was protected from grazingnorthern wheatgrass increased in cover. The higher elevation of these sites may restrict access to wild ungulategrazing. Consequently, it would appear this community type is not grazed as heavily as the Fringed sage/Junegrasscommunity type.

n=2 The two stands described in this community type are from dry, level areas in the Athabasca and NorthSaskatchewan river valleys near Jasper and Saskatchewan crossing. They are similar to the Fringed sage/Junegrasscommunity type, but lack cover of fringed sage. Small leaved everlasting is known to be well adapted to xericmoisture conditions (Moss 1992) and is known to increase with increased grazing pressure (Stringer 1973, Baileyet al. 1992).

A6. Kentucky bluegrass-Junegrass/Dandelion(Poa pratensis-Koeleria macrantha/Taraxacum offincinle)

n=3 This community type was described on lower to level slope positions, with submesic to mesic moistureregimes. The presence of a high cover of Kentucky bluegrass is indicative of the heavy grazing influence on thiscommunity type. On mesic to subhygric sites in the fescue grasslands heavy grazing pressure is known to causea decline in native grass species allowing Kentucky bluegrass to increase (Willoughby 1992). The presence ofjunegrass indicates that this community has some affinity with the Fringed sage/Junegrass community found in thesame area. In the absence of grazing this community type may resemble a Rough fescue/Upland sedge communitydescribed on hill crests in the Porcupine hills (Willoughby 1992).

The presence of this community type in theYa Ha Tinda indicates that many of the grasslands in this area are transitional to the Upper Foothills and Subalpinesubregions. Morgantini and Russell (1983), found that elk preferred the rough fescue dominated areas over thesetufted hairgrass dominated communities at Ribbon flats just west of the Ya Ha Tinda. As a result this communitytype would be rated as secondary or non-use range for elk and horses in the Ya Ha Tinda area.

A10. Bog birch/Sedge-Rough fescue(Betula glandulosa/Carex spp.-Festuca scabrella)

n=1 This community type represents the invasion of bog birch onto the rough fescue grasslands. Thiscommunity type is found scattered throughout the grasslands in the Ya Ha Tinda on slightly moister sites. It alsoappears to be transitional to many of the forested stands in the area. This community type is very similar to the Bogbirch/Rough fescue community type described by Willoughby (2001) in the Upper Foothills subregion. They feltthat the lack of fire on this community type allowed bog birch cover to expand, reducing forage productivity forwildlife and domestic livestock. In one study, burning bog birch twice in 3 year intervals controlled birch growthand increased total forage production by over 40% compared to the unburned control (Bork 1990).

A11. Rough fescue-Fringed brome-Sedge(Festuca scabrella-Bromus ciliatus-Carex spp.)

n=5 This community type represents coarse textured fluvial areas and moister south and west facing slopes.The increased moisture on these spots favours the growth of fringed brome. On the drier south and west facingslopes these grasslands are dominated by rough fescue, sedge and junegrass. The forage production on thiscommunity type tends to be slightly higher than the Rough fescue-Sedge-Junegrass dominated community type. Making this community type one of the most important foraging areas for wildlife. The rough fescue grasslandsin the Ya Ha Tinda area are extensively utilized by elk and domestic horses. It is not clear how this heavy grazingpressure has affected the species composition of these grasslands. It is likely that rough fescue cover would increaseif the grazing pressure was reduced on these grasslands (Willoughby 1992).

A12. Rough fescue-Sedge-Junegrass(Festuca scabrella-Carex filifolia-Koeleria macrantha)

n=2 This community type is distinguished from the other rough fescue dominated community type by the lackof fringed brome and the increased cover of junegrass. This community type tends to occupy steeper, morainal andcolluvial slopes and and has a drier moisture regime than the previously described rough fescue community type.Morgantini and Russell (1983) found that the rough fescue dominated community types were the primary foragingareas for elk. As a result this community type should be rated as primary range. The rough fescue grasslands inthe Ya Ha Tinda area are extensively utilized by elk and domestic horses. It is not clear how this heavy grazingpressure has affected the species composition of these grasslands. It is likely rough fescue cover would increaseif the grazing pressure was reduced on these grasslands (Willoughby 1992).

A13. Sedge-Junegrass(Carex filifolia-Koeleria macrantha)

n=2 This community type was described on the west side of the Ya Ha Tinda ranch. It is closer to the ranchbuildings and therefore is more extensively utilized by horses. It was described on coarse textured fluvial areas.The parent material and ecological conditions are similar to the Rough fescue-Fringed brome-Sedge dominatedcommunity type. It appears that the heavier grazing pressure on this community type causes rough fescue todecline and allows sedge and junegrass to increase. The forage production on this community type is about halfof the rough fescue dominated community types, indicating that some type of rest would benefit this grassland.

A14. Creeping red fescue-Timothy(Festuca rubra-Phleum pratense)

n=2 This community type represents spruce cutblocks that were harvested and seeded to creeping red fescueand timothy. This seeding was done in order to increase the forage supply for wintering elk and alleviate thepressure on the rough fescue dominated grasslands around the Ya Ha Tinda ranch. This seeding has increased theforage supply of the area, but it has been found that elk do not perfer to graze these sites. The agronomic speciesseeded into these cutblocks have also been found to be invasive (Gerling et al. 1996). Further range improvementshould probably be done with a native seed mix.

B1. Rough fescue-Idaho fescue-Parry oatgrass(Festuca scabrella-Festuca idahoensis-Danthonia parryii)

n=106 This community appears to be the modal grassland community type on Black Chernozemic soils in thefoothills of southern Alberta from an elevation of 1300m up to 1900m on isolated sites. Willoughby (1992),described one Rough fescue-dominated site where the species composition had not changed in over 30 years,indicating this maybe the climax community type on river terraces and south facing slopes in the Montane. IndeedMoss and Campbell (1947), found that rough fescue grows almost to the exclusion of other plants in the absenceof disturbance. On rocky and gravelly slopes with shallow soils, rough fescue is replaced by Parry oatgrass andIdaho fescue. They also found Parry oatgrass and Idaho fescue increased and rough fescue declined with increasedgrazing pressure. Willoughby (1992), also described rough fescue and Idaho fescue dominated community typeswith little Parry oatgrass in the Castle area south of Blairmore. He also found that rose and shrubby cinquefoiltended to increase in cover at higher elevations in these grasslands. In this guide it was difficult and impracticalto distinguish these community types. Consequently, the Rough fescue, Rough fescue-Idaho fescue and Roughfescue-Parry oatgrass/Shrubby cinquefoil-Rose community types listed in Willoughby (1992) are grouped into thisone large community type.

B2. Idaho fescue-Parry oatgrass-Rough fescue(Festuca idahoensis-Danthonia parryi-Festuca scabrella)

n=56 This community type is found upslope from the Rough fescue-Parry oatgrass-Idaho fescue communitytype (Figure 1) and can be dominated by Idaho fescue or Parry oatgrass. As one moves upslope to drier conditionsthere is a shift in species composition from rough fescue to Parry oatgrass and Idaho fescue. Under grazingpressure Parry oatgrass, Idaho fescue and rough fescue decline and upland sedge increases (Willoughby 1992).On drier sites within this community type juniper and bearberry cover can be extensive. Increased grazing pressureon the drier sites will lead to an increase in low growing forbs (little clubmoss, moss phlox) and sedges.

B3. Bluebunch wheatgrass-Sedge(Agropyron spicatum-Carex obtusata)

n=27 Bluebunch wheatgrass dominated sites are found on well-drained, south facing-slopes in the Montanesubregion throughout southern Alberta (Strong 1992). This dominant species is abundant in the interior of southernBritish Columbia, where it is codominant with big sagebrush (Artemisia tridentata) at lower elevations and roughfescue at higher elevations (Tisdale 1947). Increased grazing pressure on the drier sites leads to a decline inbluebunch wheatgrass and allows low growing forbs and sedge species to increase. On sites with big sagebrushin British Columbia bluebunch wheatgrass decreases and big sagebrush will increase with increased grazingpressure (Tisdale 1947). Forage production on this type can vary from 700 kg/ha on dry sites to over 2000 kg/haon moister sites.

B4. Rough fescue-Sedge/Bearberry(Festuca scabrella-Carex obtusata/Arctostaphylos uva-ursi)

n=49 This community appears to be characteristic of dry grass meadows on hilltops throughout the Montanesubregion. It is similar to the Rough fescue-Sedge community type described by Willoughby (1992) on hilltopsin the Porcupine Hills. The shallow poorly developed soils appear to favour rough fescue, slender wheatgrass andsedge over Parry oatgrass. This community is drier than the Rough fescue grasslands characteristic of lower slopepositions, but is moister than the bluebunch wheatgrass plant community that is associated with dry southerlyslopes. This community type can be invaded by aspen to form the Aspen/Saskatoon/Sedge, Pl/Bearberry-Juniperor Fd/Hairy wildrye community types. The transition community between the forest and grassland may resemblethe Pinegrass-Hairy wildrye or Saskatoon-Rose-Snowberr/Bearberry community types.

B5. Big sagebrush/Bluebunch wheatgrass-Sedge (Artemisia tridentata/Agropyron spicatum-Carex spp.)

n=4 This community type is rare in Alberta and is isolated on gravelly south facing slopes in the Montanesubregion south of Blairmore. This community type is similar to the Pacific Northwest Bunchgrass type describedby Tisdale (1982) in Washington and British Columbia. The big sagebrush, bluebunch wheatgrass community typesfound in these areas are located on Dark Brown and Dk Gray Chernozemic soils, with glacial till parent material(Green and van Ryswyk 1982). Tisdale (1982), found that there is little known about the environmental factorswhich determine the presence of sagebrush-grass versus true grassland. Therefore, it is not clear why these southfacing slopes are dominated by sagebrush and not a bluebunch wheatgrass community type. It is known thatincreased grazing pressure on a Big sagebrush/Bluebunch wheatgrass in British Columbia will allow big sagebrushto increase in cover, but heavy grazing pressure does not seem to be a factor in the formation of this community typein Alberta.

B6. Saskatoon-Rose-Snowberry/Bearberry(Amelanchier alnifolia-Rosa acicularis-Symphoricarpos occidentalis/Arctostaphylos uva-

n=32 This community type represents the ecotone between rough fescue dominated grasslands and Douglas firand lodgepole pine dominated forests on dry south facing slopes. The presence of shrubs (saskatoon, rose,snowberry) and the grass species (hairy wildrye, pinegrass) indicate the transition from rough fescue grasslands toa forested community type. This community type appears to occur at higher elevations (>1500m) and may reflectthe dominance of trees at the higher altitudes. Forage production declines rapidly moving from the grassland intothe forests. This community type has half the production (1100 kg/ha) of rough fescue dominated grasslands (2200kg/ha). The increase in tree canopy cover results in a further decline in forage production to approximately 600kg/ha.

B6a. Snowberry-Rose-Saskatoon(Symphoricarpos occidentalis-Rosa acicularis-Amelanchier alnifolia)

n=27 This community type represents moist pockets of shrubland in gullies and depressional areas within roughfescue dominated grasslands. This community type is very similar to the previously described Saskatoon-Rose-Snowberry/Bearberry dominated community type, but this site is moister and lacks the cover of bearberry. Thesesites will eventually become invaded by aspen to form the Aw/Snowberry or Aw/Rose/Pinegrass dominatedcommunity types.

B7. Pinegrass-Hairy wildrye/Strawberry (Calamagrostis rubescens-Elymus innovatus/Fragaria virginiana)

n=11 This community type represents the transition from grassland to forest on moist sites with northerlyaspects. It appears this community occurs in areas that have some seepage throughout the growing season. Thereis usually high forb cover on these sites with strawberry, showy aster, American vetch, peavine and silkyperennial lupine being common. Pinegrass and hairy wildrye are the common grass species in the understory ofconifer and deciduous stands and their dominance in this community type may indicate a transition to a forestedcommunity. The high moisture content of these sites allows for production of over 2000 kg/ha.

B8.Douglas fir/Idaho fescue-Rough fescue(Pseudotsuga menziesii/Festuca idahoensis-Festuca scabrella)

n=5 This community type represents the transition from grassland to a Douglas fir dominated forest. Thefactors responsible for the differences between forest and grassland maybe climatic, with cooler and moisterconditions favouring forest, it could be edaphic with grasslands found on drier and shallower soils or lack ofdisturbance from fire which favours the growth of trees. Extensive overlap of the forests and grassland will occurin the Montane because of the variable soils and topography.

B9.Douglas fir/Idaho fescue-Sandberg bluegrass(Pseudotsuga menziesii/Festuca idahoensis-Poa sandbergii)

n=1 This community type is similar to the Douglas fir/Idaho fescue-Rough fescue community type andrepresents the transition from grassland to forest, but this type is drier and has shallower soils than the Douglasfir/Idaho fescue-Rough fescue community type. Little clubmoss, fringed sage, Sandberg bluegrass and junegrassare all well adapted to dry, rapidly drained sites. Johnston (1981), described a Sandberg bluegrass/Bluebunchwheatgrass type on dry sites with extremely shallow soils in Oregon and Tisdale (1982) described Sandbergbluegrass on dry sites with fine textured soils in British Columbia. It is also possible that increased grazingpressure may also account for the high cover of Sandberg bluegrass. Mueggler and Stewart (1980), found Sandbergbluegrass increased with grazing pressure on dry grasslands in Montana.

B10. Aw/Strawberry/Rough fescue(Populus tremuloides/Fragaria virginiana/Festuca scabrella)

n=2 This community type represents the transition from a rough fescue dominated grassland to an aspen dominatedforest. Aspen has invaded onto the grassland and the species composition of the understory is slowly succeeding tospecies characteristic of aspen stands such as strawberry and slender wheatgrass.

This community type is much moister than the Douglas fir transition forests previously described. Aspen favorsthe moist draws and north-facing slopes throughout the foothills of southern Alberta. As one moves west into themountains and the Subalpine subregion, aspen tends to grow very poorly, and the aspen stands are characterized bystunted, twisted trees that have low vigour. Forage production on the grasslands declines rapidly when aspen invades;from a high of 2000 kg/ha to a low of 1000 kg/ha.

n=3 This community type is characteristic of nutrient-rich seepage areas throughout the Montane. This communityis very similar to the Aw-Pb/Thimbleberry and Lodgepole pine/Thimbleberry community types described later in theguide, but it is not as successional advanced.

Forage production of this community type is very high because of the high moisture and nutrient content of thesoil, but the thick cover of thimbleberry which is generally unpalatable to livestock at proper stocking levels limits access.As a result this community type should be rated as non-use range.

n=8 This community type is found in all subregions of Alberta. Wet conditions and periodic flooding result in theformation of sedge meadows. Bog birch and willow will invade into the drier edges of these meadows to form theWillow/Sedge and Bog birch /Sedge community types.

These community types are quite productive producing nearly 2000 kg/ha of forage, but the high water tablein the spring and summer when these meadows are most palatable limits livestock use. A study in the Yukon found thatcrude protein on these meadows declined from a high of 10% in May to less than 5% in September (Bailey et al. 1992).As a result, these meadows would be rated as secondary or non-use range.

n=3 This community type is found in all subregions of Alberta. Wet conditions and periodic flooding result in theformation of sedge meadows. Bog birch and willow will invade into the drier edges of these meadows to form theWillow/Sedge and Bog birch /Sedge dominated community types. Thompson and Hansen (2002) described thiscommunity on the eastern edges of the Montane subregion. They found this community in lentic situations arounddepressional wetlands, sloughs, potholes on sites that were generally more alkaline than the Beaked and Water Sedgedominated meadows. Willoughby (2001) has found this sedge species to be very palatable to livestock in the UpperFoothills subregion. If the sites dry out they can be extensively utilized by livestock.

These community types are quite productive producing nearly 2000 kg/ha of forage, but the high water tablein the spring and summer when these meadows are most palatable limits livestock use.

n=2 This community type is very similar to the tufted hairgrass-dominated communities described in the Upperfoothills and Subalpine subregions of northern Alberta (Willoughby 2001) and may indicate the transition from theMontane to the Subalpine subregion in southern Alberta. This community is located on moist sites that are better drainedand slightly drier than the pure sedge meadows. When this community is protected from grazing and fire for 25-40 yearswillow and bog birch expand and tufted hairgrass and sedge decline. The decline in graminoid cover causes a declinein available forage production.

B14. Forb meadows(Aster ciliolatus, Monarda fistulosa,Smilacina stellata)

n=2 This community type represents small isolated forest openings that are dominated by forbs. The sites tend tobe moist , moderately well drained and probably have some nutrient seepage at some time in the year. These meadowscan be dominated by Lindley's aster, wild bergamont, or star flowered solomon’s seal. The grass layer is generally poorlydeveloped which makes this community type hard to group with any of the grassland community types.

The forage production of this community type is generally quite high because of the higher moisture and nutrientcontent of the soil, but the areas are so small and isolated they contribute little to the overall carrying capacity of adisposition.

B15. Rough fescue-Hairy wildrye(Festuca scabrella-Elymus innovatus)

n=2 This community type was described on the east slopes of the Livingstone range and appears to represent atransitional community from the lower Montane subregion to the higher Subalpine region. Indeed Willoughby(1999)described a Rough fescue-Hairy wildrye community type in the southern subalpine. They felt that as one moved upslopethere would be a shift in codominance of sedge to hairy wildrye and an increase in cover of bearberry and juniper. Cornsand Achuff (1982), described hairy wildrye dominated community types on south facing slopes in the more northernecodistricts of the subalpine. They felt these grasslands occurred on areas with frequent snow avalanching. It is possiblethat this community type is associated with deeper snow accumulation than the other rough fescue dominated types.

B16. Big sagebrush-Buckthorn/Kentucky bluegrass(Artemisia tridentata-Rhamnus alnifolia/Poa pratensis )

n=2 This community type was described on the valley bottoms and meadows adjacent to the South Castle river. Buckthorn tends to grow in the moist areas of the meadows which have fine textured soils. In contrast big sagebrushis found on the drier, gravelly soils of old creek beds. These meadows have been extensively utilized by livestock andrecreationists which has allowed Kentucky bluegrass, timothy and dandelion to become established in the understoryof these shrub species. It is difficult to determine what the understory vegetation was prior to disturbance. It is felt thatthis site was probably dominated by rough fescue, but the presence of dark scaled sedge and graceful sedge appear toindicate a higher moisture regime than rough fescue-dominated communities. The establishment of an exclosure toprotect the site from disturbance may help to answer this question.

DISTURBED GRASSLAND COMMUNITY TYPES

Photo 6: The dominance of Kentucky bluegrass, dandelion and clover indicate that this is anovergrazed grassland. Once Kentucky bluegrass has established dominance, the site will notreturn to the original vegetation composition when protected from grazing. Instead it will moveto another community type, dominated by Kentucky bluegrass and native species such as roughfescue.

C1. Idaho fescue-Parry oatgrass-Sedge(Festuca idahoensis-Danthonia parryi-Carex obtusata)

n=32 This community type represents a Rough fescue-Idaho fescue-Parry oatgrass plant community that hasbeen moderately to heavily grazed for a number of years. The species composition of this community is verysimilar to the Idaho fescue-Parry oatgrass-Rough fescue community types , but this community type occupies lowerslope positions, whereas the latter community occupies mid to upper slope positions.

Increased grazing pressure causes rough fescue to decline and allows Idaho fescue, Parry oatgrass andsedge species to increase. Continued heavy grazing pressure will eventually lead to a decline in all native speciesand Kentucky bluegrass and dandelion will dominate the site. If grazing pressure on this community type is reducedor is eliminated the type will likely succeed back to a rough fescue dominated grassland. However, if the presentgrazing pressure continues Kentucky bluegrass will likely dominate the site. Recovery of this grassland back toa rough fescue dominated community type will likely take 20-30 years (Willoughby 1996).

C3. Kentucky bluegrass-Rough fescue(Poa pratensis-Festuca scabrella)

n=70 Long-term heavy grazing pressure leads to decline in rough fescue and an increase in Parry oatgrass andsedge species. Continued grazing pressure reduces the competitive advantage of rough fescue and the other nativegrass species and allows Kentucky bluegrass to establish on the site. Continued heavy grazing pressure eventuallyleads to a decline in all native species and the plant community will resemble a Timothy-Kentucky bluegrass/Dandelion type.

The shallow, nutrient poor soils of the Canada bluegrass dominated community type do not appear tofavour the growth of Kentucky bluegrass under similar grazing conditions and may explain the lack of Kentuckybluegrass in the Canada bluegrass-Rough fescue-Slender wheatgrass community type..

The forage productivity of this community type (2600 kg/ha) is equivalent to or better than a lightly grazedRough fescue-Parry oatgrass community (2015 kg/ha). However, rough fescue is a much more desirable foragespecies because it maintains its nutrient content into the dormant season. In contrast, Kentucky bluegrass loses itspalatability, and nutrient content if it is allowed to flower and set seed.

C4. Kentucky bluegrass-Timothy/Dandelion(Poa pratensis-Phleum pratense/Taraxacum officinale)

n=80 This community type appears to once have represented a Rough fescue-Parry oatgrass-Idaho fescuecommunity type on Black Chernozmic soils. Conitunued heavy grazing at the beginning of the century has shiftedthe community to one dominated by Kentucky bluegrass, timothy and dandelion.

The climax range condition model suggests that vegetation development will be directional, predictableand revert to the original vegetation when protected from grazing, but once Kentucky bluegrass has established,bluegrass appears to compete with rough fescue for codominance. When protected from grazing these Kentuckybluegrass dominated types move toward a different community type rather than back to the original vegetation.These sites closely follow the "State transition model" proposed by Westoby et al. (1989).

C7. Creeping red fescue/Dandelion-Clover(Festuca rubra/Taraxacum offincinale-Trifolium repens)

n=10 This community is an example of a rough fescue grassland which has been modified during reclamationof a natural gas pipeline and power transmission lines. Seed from the reclamation has influenced the plantassociation such that creeping red fescue and Kentucky bluegrass now dominate the site. Previously tame specieslike creeping red fescue were used in reclamation with little thought given to compatibility with surrounding nativevegetation. It is now recognized that native species that promote the recovery of the original community structureand function should be used in reclamation (Gerling et al. 1996).

C8. Northern wheatgrass-Kentucky bluegrass (Agropyron dasystachyum-Poa pratensis)

n=1 This community type is found on a dry, moderately to heavily grazed, south-facing slopes with shallowsoils above the Oldman river in the Outer Gap range allotment. The moisture regime is not high enough to allowcomplete invasion of Kentucky bluegrass and dandelion . In the absence of disturbance the community type wouldprobably resemble moister sites within the Bluebunch wheatgrass-Sedge community type.

The Outer Gap allotment is subject to extremely high, dessicating winds. As a result, the climate is verysimilar to the grasslands described in Rocky Foothills and Rocky Mountain ecodistricts. Indeed many of thespecies characteristic of the grasslands described in these ecodistricts (junegrass, northern wheatgrass, blunt sedge,small leaved everlasting) are found in this community type.

C9. Rough fescue-Kentucky bluegrass(Festuca scabrella-Poa pratensis)

n=28 This community type represents grasslands that have been grazed heavily to the point of Kentuckybluegrass invasion and are now recovering, or ungrazed exclosures that have been invaded by Kentucky bluegrass.Long-term heavy grazing pressure leads to a decline in rough fescue and an increase in Parry oatgrass and sedgespecies. Continued grazing pressure reduces the competitive advantage of rough fescue and the other native grassspecies and allows Kentucky bluegrass to establish on the site. Protection or a reduction in stocking level at thepoint where Kentucky bluegrass has become a significant component of the community allows rough fescue torecover, but it seems Kentucky bluegrass also remains as codominant. Willoughby (1996), found that somerangeland reference area sites which were protected from grazing before Kentucky bluegrass became establishedrecovered to Rough fescue-Idaho fescue-Parry oatgrass in 20-30 years. In contrast sites that had significantKentucky bluegrass invasion recovered to Rough fescue-Kentucky bluegrass dominated sites over the same timeperiod. It appears that both the unidirectional climax range condition model proposed by Dysterhuis (Wroe et al.1988) and the State and Threshold model proposed by Westoby et al. (1989) apply to the successional sequencesof the rough fescue grasslands of southwestern Alberta. This makes it extremely difficult to assess range healthon these sites (Willoughby and Alexander 2000). That is why the Ecological site and Desired Plant communityconcepts proposed by the Task Group on Unity in Concepts and Terminology (1995) have been adopted todetermine range health on these rangelands.

C11. Snowberry/Kentucky bluegrass(Symphoricarpus occidentalis/Poa pratensis)

n=3 This community type was described on lower slope positions along the valley bottoms of the PorcupineHills. The increased moisture content on these sites favours the growth of snowberry which has slowly invadedinto the surrounding grasslands. Snowberry is common in the understory of many aspen communities throughoutthe Montane subregion. It is likely this community type will eventually become dominated by aspen.

The high moisture and nutrient content of the site make this a very productive community type, but thehigh snowberry cover limits its use by livestock. Snowberry is very resistant to fire and sprouts readily afterburning. It has been found that mowing followed by herbicide treatment is effective in controlling snowberrygrowth.

MONTANE SHRUBLAND ECOLOGYShrubland communities in the montane subregion of Alberta occur in valley bottoms,

depressional areas, and on moist upland seepage areas. They are highly diverse and dynamiccommunities that represent transition from wetland to forest or seral stages of developmentfollowing disturbance. The Green alder-Scouler's willow-Wild red raspberry, Bebb willow/Hairywild rye and Hawthorn-Snowberry/K. bluegrass community types are found on moist, upland sites.They represent seral stages of development following disturbance. The Green alder-Scouler'swillow-Wild red raspberry community type is found on moderate northerly slopes and the Beakedwillow/Hairy wild rye community type is found on south-facing slopes with high moisture andnutrient regimes. The Hawthorn-Snowberry dominated community is often associated with smalldrainages and seepage areas. These upland shrublands provide excellent forage for wildlife in theearly stages of succession.

Lowland shrublands are found in low, marshy or bog sites and are often considered theedaphic climax communities on these sites since the wet cool soil conditions often preventsuccession to forest. However, where organic matter begins to accumulate and the site becomesdrier, succession to either black spruce or white spruce will occur. The extent of the shrub cover ishighly dependent on the water level. Colonization by willow and other shrubs such as dwarf andbog birch begins on the drier edges of sedge meadows and streams. This colonization expands ifthe water level decreases, but declines under prolonged exposure to flooded conditions. Theunderstory species most often associated with these shrublands include wire rush, beaked sedge,water sedge, other wetland sedges, and horsetail on the wettest sites. Bluejoint, slender wheatgrass,shrubby cinquefoil, and upland sedges are found on the more mesic, better drained sites. The betterdrained sites often have a Bebb willow overstory. Where water sedge and/or golden moss aredominant in the understory of the Sw/Willow/Water sedge/Golden moss community, indicates acalcium-rich environment, often with stagnant water (Beckingham, 1994; MacKinnon et. al., 1992).A dominance of beaked sedge in the understory of the Basket, Flat leaved or Bebb willowdominated communities, indicates nitrogen-rich conditions with flowing water (Beckingham, 1994). Bluejoint can also be a common understory species on the better-drained sites in these communitytypes. It appears that tufted hair grass will replace bluejoint on similar sites as elevation increases(Lane et. al., 2000).

The shrublands found adjacent to riparian areas occur on well-drained, coarse-textured soils. River alder indicates a seepage area when found on a slope as in the Yellow mountain avens-Riveralder/Low forb community type. Elsewhere, it grows best on poorly-drained, lower slope positions.Yellow mountain avens is a common pioneer species on gravelly river bars and rocky slopes andgrows especially well on calcium-rich soils (MacKinnon et. al., 1992). Silverberry and Drummond’swillow are also common in these riparian areas. Both these species prefer well-drained, coarse-textured soils. The riparian shrublands described here will eventually succeed to white spruce inthe absence of disturbance.

Increased grazing pressure tends to allow Kentucky bluegrass and timothy to invade theunderstory of many of these shrub dominated communities. The high moisture and nutrient contentof these sites makes them very productive for livestock grazing.

D1. Yellow Mountain Avens-River Alder/ Low Forb(Dryas drummondii-Alnus tenuifolia/Low forb)

n=1 This community type is found on an open, south-facing slope which supports a few scattered balsam poplartrees. The abundance of river alder and presence of balsam poplar indicates that this is a moist, nutrient-rich seep.In contrast yellow mountain avens grows favorably on open, well-drained sites and is typical of dry, gravelly riverflats throughout Alberta. Willoughby (2001) described a Balsam poplar-White spruce/Willow/Yellow mtn. avenscommunity type that is similar, but successionally more mature in the Upper Foothills subregion. In the absence ofdisturbance, river alder and balsam poplar will increase causing mountain avens to decrease as the site becomesshaded. Eventually this site will succeed to white spruce forest. This community type would be found upslope fromthe Yellow mtn. avens-Silverberry/Junegrass community type (D2) which is found on the level river flats.

D2a: Drummond’s willow(Salix drummondiana)

n=1 This community type was described next to the Oldman river on a recent river bar that is periodicallyflooded. Drummond’s willow is well adapted to growing in a variety of soil conditions, but it prefers growing onwell aerated soils. It is well adapted to growing at higher elevations and is often associated with the subalpine.Drummond’s willow communities tend to be long-lived and are often maintained by frequent flooding. If the watershifts and the site drys out it will often undergo succession to a white spruce dominated forest. The dense natureof this community type often limits livestock movement. It should be rated as non-use.

D3: Beaked Willow/Hairy Wild Rye(Salix bebbiana/Elymus innovatus)

n=2 This community type represents a drier upland willow type which can be found on north-facing slopes, ravinesand seepage areas. This community type was described in Banff and Jasper National Parks. The moisture and nutrientregimes favor an abundance of willow and the presence of a few scattered spruce trees. Beaked willow is highlypalatable to wild ungulates, therefore, this community should be considered important wildlife habitat. In the absenceof disturbance, this community type will likely succeed to white spruce.

D3a: Bebb willow/Marsh reedgrass(Salix bebbiana/Calamagrostis canadensis)

n=1 This community type was described at Beauvais Provincial Park. It represents a mosaic of willow clumpsamid a mainly graminoid matrix. In general Bebb willow is often associated with better drained soils than theBasket or Flat leaved willow dominated community types. The presence of Baltic rush and marsh reedgrassindicates that this site is better drained than the Basket and Flat leaved willow/ Sedge dominated community typesdescribed later in the guide. The open nature of this site and the drier site conditions would favour livestock use.Heavy livestock use will favour the growth of Kentucky bluegrass and timothy and would resemble the Bebbwillow/Kentucky bluegrass dominated community type.

D4: Bebb willow/Kentucky bluegrass(Salix bebbiana/Poa pratensis)

n=11 This community type is very similar to the Bebb willow/Hairy wild rye or Bebb willow/Marshreedgrass community type, however, this community type has been altered by grazing. The grazing pressurehas promoted the establishment of timothy, Kentucky bluegrass and dandelion. These sites are often veryproductive because of the higher nutrients and moisture and once Kentucky bluegrass and timothy becomeestablished these sites will be readily grazed by livestock. In the absence of disturbance this type will likelysucceed to white spruce.

D5: Green Alder-Scouler's Willow-Wild Red Raspberry(Alnus crispa-Salix scouleriana-Rubus idaeus)

n=2 This community type is generally found on mesic to hygric lower subalpine sites on moderate northerlyslopes. Soils are moderately well to well-drained on morainal landforms with the community occurring in seepageareas (Corns and Achuff, 1982). This type is similar to Jaques and Corbin's (1981) Scouler's willow-Beaked willowtype. It is also comparable to the Willow-Alder-Low bush cranberry/Shield fern type described by Lane et al. (2000)in the Lower Foothills subregion on similar site types. Salix scouleriana dominates the overstory and alder makesup a major portion of the understory cover. Dominance of alder may indicate a recent fire or other disturbance in theunderstory since alder regenerates faster than Salix scouleriana. White spruce, aspen, balsam poplar and lodgepolepine can often be found regenerating in this community type, therefore this community type will likely succeed towhite spruce (Corns and Achuff, 1982).

D6: Flat-Leaved Willow/Quackgrass-Kentucky Bluegrass(Salix planifolia/Agropyron repens-Poa spp.)

n=2 This community type represents a disturbed willow shrubland. Salix planifolia prefers areas where thewater table is shallow, and is found adjacent to riparian areas, fens, swamps and lakeshores. Heavy grazing of thistype has affected the understory vegetation allowing an increase in quackgrass and Kentucky bluegrass on the drierareas. The proximity to water and shallow water table would explain the heavy use by livestock as well as the highproduction. Care must be taken to ensure that the riparian habitat is not over-used by livestock.

n=6 This is a highly unusual community type for the montane. It will likely only be found at the lowerelevational limits of the montane subregion. Corns and Achuff (1982) describe this community type on hygric, levelto gently sloping fluvial landforms of various aspects. The soils are imperfectly to poorly drained and are subjectto periodic flooding and sediment deposition. Tree cover is absent and willow cover is high. Field horsetail is thedominant herb. Other species may also be found, such as dwarf shrubs and sedges, however, these are minorcomponents.

D8: Myrtle leaved willow/Sedge(Salix myrtillifolia/Carex rostrata)

n=12 This community type is similar to the Willow-Bog birch/Sedge community type of Lane et al (2000). Itrepresents a typical willow/sedge community type found on wet, poorly drained soils. There are numerous differentspecies of willow as a result of the open canopy and the wet moisture regime. A high cover of beaked sedgeindicates a nitrogen-rich environment where the water is moving. Tufted hair grass (Deschampsia cespitosa) willreplace marsh reedgrass in this community type at higher elevations (Lane et al, 2000). This would be consideredan edaphic climax community since the area is frequently flooded which prevents establishment of trees althoughit may be found in association with black spruce and black spruce-larch community types. This community typewould be considered non-use for livestock due to the poor access caused by the wet substrate.

D12: Black Spruce/Myrtle-Leaved Willow/Wire Rush-Sedge/Moss(Picea mariana/Salix myrtillifolia/Juncus balticus-Carex spp./ Moss spp.)

n=3 This community type represents a wet willow shrubland succeeding to black spruce. It is most simlar to theBog birch-Basket willow-Myrtle-leaved willow community type (D9), however this one is successionally moreadvanced. Salix myrtillifolia is characteristic of mossy bogs, muskegs and moist conifer forests (Jaques and Corbin,1981). This would be considered non-use for domestic livestock and wildlife because Salix myrtillifolia is generallyunpalatable.

D13: Water birch-Smooth willow/Pinegrass(Betula occidentale-Salix glauca/Calamagrostis rubescens)

n=1 This community was described on a hilltop depression which supports a high moisture and nutrientregime. The depression also provides protection from the prevailing winds. Therefore, shrubs are abundant,however, due to wet conditions at the bottom of the depression, trees will likely only develop on the drier edges. The surrounding wind-exposed areas support grassland vegetation, therefore, this community type wouldprovide good shelter for livestock later in the fall when the site had dried.

n=2 This community can be found on alluvial terraces along streams and rivers or on slopes immediatelybelow a spring or seep (Thompson and Hansen 2002). Thompson and Hansen (2002) described this communitytype in the Cypress Hills, but it has been observed in the Castle and South Castle drainages. Where thiscommunity type forms dense thickets there is little use by livestock. However, severe prolonged disturbance inthe more open stands can lead to the invasion of Kentucky bluegrass and timothy to form this community type. Succession in the absence of disturbance will likely be to aspen and then white spruce.

MONTANE FOREST ECOLOGY

The Montane subregion is distinguished from other subregions by having two distinctecological sequences: Douglas-fir (Fd) and limber pine (Pf) in one sequence, and lodgepolepine(Pl) in another (Figure 4). Douglas-fir is the climax species on steep, south-facing, shallowrocky soils, and very coarse-textured outwash in valley bottoms (Strong 1992). Limber pineoccupies exposed rocky outcrops where the environmental conditions are extreme. These sitesare very xeric with shallow, poorly developed soils. Kuchar (1973) noted that the limber pine inAlberta is found at the northern limit of its range since it is found well below timberline. It isnormally associated with high elevations or timberline south of Alberta where it takes on akrummholz form (dwarfed, contorted form, maintained by strong winds).

Closed-canopied lodgepole pine stands represent the primary reference vegetation for themontane subregion, since they often occur on mesic sites (Strong 1992). In contrast, closed-canopied aspen(Aw) stands tend to occur on sites that are warmer and drier than the referencesites (Strong 1992). Douglas-fir and white spruce(Sw) represent the potential climatic climaxspecies for both lodgepole pine and aspen stands (Strong 1992; La Roi and Hnatiuk 1980). Balsam poplar(Pb), however, occupies the moistest sites and will succeed to white spruce sincethe high moisture content is not conducive to Douglas-fir succession.

Common understory species include thimbleberry, creeping mahonia, Canadabuffaloberry, bearberry, snowberry and white meadowsweet. These species tend to define theecosites and ecosite phases as described by Archibald et al. (1996). Thimbleberry and creepingmahonia are more common in the Castle area of the province. Moving north of Blairmore in theMontane thimbleberry is often replaced by cow parsnip and creeping mahonia by whitemeadowsweet on similar ecosites.

Many of the forested communities at lower elevations (1400-1500 m ) in the Castle areawere dominated by subalpine species (subalpine fir(Fa), Engelmann spruce(Se)), whereas theMontane grasslands in this area were described up to elevations of 2000 m. This resulted in abroad range of characteristic species on modal sites. Archibald et al. (1996) felt there had to befurther refinement of the Subalpine subregion into upper and lower latitudinal subdivisions. Clearly, this would help to refine the classification of community types in the Castle area.

The common species, canopy cover, community characteristics and productivity areoutlined.

E1: Pf/Rough fescue(Pinus flexilis/Festuca scabrella)

n=1 This community type was described on a steep, west-facing slope with a subxeric moisture regime. Thehigh cover of rough fescue distinguishes this community from other, more typical limber pine dominatedcommunity types. This community probably has deeper soils and is likely protected to some extent from the dry,dessicating winds that are normally associated with limber pine community types (Corns and Achuff 1982). Theseconditions would favour the growth of rough fescue.

E2: Pf-Fd/Juniper/Bearberry(Pinus flexilis-Pseudotsuga menziesii/Juniperus communis/Arctostaphylos uva-ursi)

n=6 This community type occurs on steep, exposed ridge tops and upper slope positions within the montanesubregion. It is characterized by dry site conditions and exposure to westerly winds. Soils are often shallow to bedrock(Archibald et al 1996), This community often forms an edaphic climax on these sites. Limber pine is normally associatedwith high elevations or timberline where it attains a Krummholz form (Kuchar 1973). However, the montane regionsof Southwestern Alberta are found at the northern limits of the range for limber pine, thus they can generally be foundat the lower elevations between prairie and coniferous forest. Limber pine, bearberry, juniper and the other associatedspecies of this community type are all well adapted to the low moisture levels, high light intensity, heat and low soilnutrient levels which occur on these erosional, south-facing scarps (Kuchar 1973). Utilization of this site by livestockis often difficult because of the steep slope. These sites are generally considered non-use.

E3: Pl/Bearberry-Juniper(Pinus contorta/Arctostaphylos uva-ursi-Juniperus spp.)

n=5 This community type is similar to the Limber pine-Douglas-fir/Juniper/Bearberry community type previouslydescribed, but occurs on slightly richer and better developed soils. Dry site conditions from south exposures or coarse-textured soils are characteristic of this community type (Archibald et al. 1996). The dry site conditions limit the amountof forage this site can produce and the steep slope limits access to livestock. As a result, this community type wouldbe considered non-use.

E4: Sw-Pl/Alder/Bearberry(Picea glauca-Pinus contorta/Alnus crispa/Arctostaphylos uva-ursi)

n=1 This community was described by Corns and Achuff (1982) in the Banff and Jasper Mountain ecodistricts.It occupies rapidly drained, level areas with a poor nutrient regime. This community is similar to Archibald et al’s.(1996) bearberry Aw-Sw-Pl ecosite phase. Succession will generally be to white spruce, but succession rates will beslow because of the dry site conditions. The presence of green alder indicates there is a higher moisture content at somepoint in the growing season, making this community type slightly moister than the modal bearberry ecosite. The hightree cover and poor nutrient status would limit the amount of forage for domestic livestock. This community wouldbe rated non-use.

n=4 This community type occurs on submesic, well drained, south and west-facing slopes. It is situated inslightly lower slope positions and therefore has better developed soils than the Limber pine and bearberry-dominatedcommunity types previously described. Archibald et al. (1996) described this community type as being part of theCanada buffaloberry-hairy wildrye ecosite. They felt this ecosite to be relatively dry for the subregion, but not asdry as the limber pine and bearberry ecosites. This community type has only sparse understory vegetation andtherefore has only limited forage for domestic livestock. It should be rated as non-use.

n=11 This community type occurs on steep, dry sites throughout the subregion. Douglas fir is usually restrictedto steep, south facing slopes, shallow rocky soils and coarse-textured outwash in valley bottoms (Strong 1992). Thesoils of this type are not as rich as the previously described Pl/Buffaloberry, but are better than the bearberry andlimber pine dominated ecosites. This community has a high cover of Douglas fir and a very sparse understory.Consquently, there is little forage available for domestic livestock.

Livestock often congregate in these open Douglas firstands on the hilltops. These sites are often windy, cool and the livestock can escape from the bugs. The heavy useon these sites favours the growth of timothy over the native grass species. These sites are quite productive and shouldbe rated as secondary range.

E8: Pl/White meadowsweet(Pinus contorta/Spiraea betulifolia)

n=6 This community is one of several community types which represent the mesic/medium ecosite for theMontane subregion. These sites can be dominated by Douglas fir, white spruce, aspen or lodgepole pine. Theunderstory can be dominated by white meadowsweet, pinegrass or feather moss depending on the successional statusof the stand. In the vicinity of the Crowsnest Pass creeping mahonia is also common on these sites (Archibald et al.1996). White meadowsweet is well adapted to growing on dry rocky slopes (MacKinnon et al. 1992). The presenceof a high cover of white meadowsweet may indicate slightly drier conditions and shallower soils than a communitydominated by pinegrass. This community type produces little forage for domestic livestock and should be considerednon-use.

E9: Pl/Pinegrass(Pinus contorta/Calamagrostis rubescens)

n=15 This community is dominated by a lodgepole pine overstory and an understory of pinegrass. Successionwill be to white spruce or Douglas fir, but the extensive fire and disturbance history in the Montane has resulted ina predominance of lodgepole pine and Douglas fir (Archibald et al. 1996). This community is also very similar tothe previously described Pl/White meadowsweet community type, but the high cover of pinegrass and low coverof white meadowsweet may indicate slightly moister, better developed soils. Pinegrass is generally unpalatable tolivestock, but if it is grazed early in the spring they will utilize it as a forage source. The forage productivity of thiscommunity type is quite low. As a result, this community should be rated as secondary or non-use.

E10a: Fd/Snowberry(Pseudotsuga menziesii/Symphoricarpos occidentalis)

n=5 This community type was described on moderate south and westerly facing slopes on the east side of thePorcupine Hills. Snowberry is generally indicative of nutrient rich seepage areas in the Montane subregion andgenerally forms thickets in the lower slope positions. The snowberry in this community type consists of smallindividual plants that are uniformly scattered throughout the community. Archibald et al. (1996) did not recognizethis community type and placed it within the hairy wildrye (submesic/medium) ecosite because of the moderateslopes the community was described on. However, the high constancy of snowberry in this community type appearsto indicate slightly higher moisture and nutrients. Consequently, this community type was placed within themesic/medium ecosite. Livestock may use these community types because of the open nature of the tree canopy, butthe forage production is only moderate and the areas where this community type were described are generallyinaccessible to livestock. As a result this community type should be rated as non-use range.

Note as succession occurs there is a corresponding drop in forageproductivity from 500-600 kg/ha in the Pl community types to 201 kg/ha in this community type. This communitytype would be rated as non-use for domestic livestock.

n=1 This community type was described by Thompson and Hansen (2002) on an old floodplain bar that was0.5 to 1.0 m above the current water table. The community represents succession to a Sw/Horsetail dominated type.As more sediment is deposited over the gravel it will favour the growth of horsetail over silverberry. Silverberryis common on gravelly river bars, but as the sediment increases and the drainage becomes poorer silverberry willdecline in cover. There is little forage available for domestic livestock in this community type and it should be ratedas non-use.

E13: Pl/Thimbleberry(Pinus contorta/Rubus parviflorus)

n=5 Nutrient rich seepage occurs on this community type at some point in the growing season favouringthe growth of thimbleberry. On these sites thimbleberry is very common south of the Crowsnest Pass and isgenerally replaced by cow parsnip north of the Pass. Succession on these sites will be from aspen to pine andthen to white spruce. Forage productivity on these sites is generally quite high because of the favourablemoisture and nutrient conditions. Thimbleberry is generally unpalatable to livestock, but if the site has anabundance of cow parsnip it may be extensively utilized. This community type should be rated as secondaryrange.

n=1 This community type is very similar to the Pl/Thimbleberry community type previously described, butcontains a high cover of beargrass. Archibald et al. (1996) recognized these beargrass-dominated community typesin the extreme southern portion of the subregion. Beargrass is well suited to growing on hillsides and drysubalpine meadows and appears to indicate the transition from the lower Montane subregion to the upper Subalpinesubregion. The tender seed pods are often eaten by small rodents and elk. In the winter Mountain goats often eatthe leaves (Craighead et al. 1963). The tough leaves of beargrass are unpalatable to livestock.

n=1 This community type is very similar to the previously described Pl/Thimbleberry andPl/Thimbleberry/Beargrass community types, but contains river alder. River alder tends to be found growing onnutrient seepage areas with high water tables. This community type is probably moister than the otherPl/Thimbleberry dominated types, but dries out at some time during the growing season which favours the growthof thimbleberry. The high cover of alder limits the light reaching the forest floor and results in low production ofgrass and forbs. The majority of the total production comes from alder which is unpalatable and generallyinaccessible to livestock. Consequently, this community type would be rated as non-use.

E17: Sb-Lt/Labrador tea(Picea mariana-Larix laricina/Ledum groenlandicum)

n=1 This community type occurs in association with lowland boggy areas. The water table under this type hasbegun to drop which has allowed succession toward a white spruce-dominated community. Generally, black spruce-larch dominated communities are considered successionally mature because of poor drainage, acidic soils and low soilnutrients which prevent succession to white spruce. This community type is likely flooded in the spring, therefore, itmay provide a scource of water for livestock early in the year. However, due to poor access and the limited number ofpalatable plants available, this community type would be considered non-use.

n=1 This community represents a subalpine forested community type with mesic moisture regimes and mediumnutrient regimes. Subalpine fir, Englemann spruce, false azalea and grouseberry rarely occur at lower elevationsand therefore are characteristic of the subalpine environment. The Castle area of the province is unusual in thatthe subalpine forested communities can be found at lower montane elevations and the montane grasslands can befound at alpine and subalpine elevations. Clearly there is a strong overlap between the Montane and Subalpinesubregions of this area of the province. It is for this reason that the forested community types for the Castle areaare described in this guide.

Succession in the subalpine is from lodgepole pine to Engelmann spruce and subalpine fir(Archibald et al. 1996). This community type appears to represent the climatic climax for sites with subalpineenvironments in the Castle area of the province. The northerly aspects of the three described sites probably allowedthem to escape the recent fire history and undergo succession. As these forested sites succeed towards climax thereis very little light reaching the forest floor. As a result, there is little forage for domestic livestock and this communitywould be rated as non-use

n=1 This community type represents an earlier successional stage of the Pl/White meadowsweet and Pl/Pinegrasscommunity types. These communities occupy mesic sites with medium nutrient regimes (Archibald et al. 1996). Itappears that this community type was grazed heavily in the past and then rested. Willoughby (1995) found that aspenstands that have been heavily grazed for prolonged periods have a low cover of native shrubs, forbs and grass species anda high cover of Kentucky bluegrass, clover and dandelion. This community has a high cover of Kentucky bluegrass, butit also has a high cover of native shrubs, forbs and grass, which may indicate that it has been grazed heavily to the pointof Kentucky bluegrass invasion and then rested allowing recovery of the native species. This community is veryproductive for domestic livestock, but Kentucky bluegrass provides a poor source of forage for wintering wildlife.

n=2 This community was described in the Castle area of the province and if left undisturbed would have likelysucceeded to a Fa-Se/Heart lv’d arnica-dominated community type. Heavy grazing pressure has shifted theunderstory away from native species and allowed dandelion, clover, Canada thistle, timothy and Kentucky bluegrassto establish on the site. This change in species composition with increased grazing pressure is similar to work doneby Willoughby (1995). The invasion of non-native species onto this site makes this community very productivefor domestic livestock, but the presence of overgrazed communities indicates some type of distribution problem andthe management of the disposition should be discussed with the permitees.

n=3 Archibald et al. (1996) described a similar Pb/Snowberry-dominated community on moist lower slopepositions where seepage occurs in the spring and after heavy rainfalls. They felt succession would be to white spruce.This community is successionally more advanced than the Pb/Snowberry dominated community type. Likely thenortherly aspects of the 3 stands described allowed this community to escape the extensive fire history in the area.The high canopy cover of trees and shrubs limits the amount of light reaching the forest floor and therefore there isonly moderate amounts of forage available for domestic livestock. This community type would be rated as secondaryrange.

F12: Sw-Aw/Scouring rush(Picea glauca-Populus tremuloides/Equisetum scirpoides)

n=1 This community occupies moist, nutrient rich, lower slope positions. This community is very similar to theSw/Horsetail community described by Archibald et al. (1996). Archibald et al. felt that the ecosite representing thiscommunity represented the wettest and most nutrient rich conditions for the Montane subregion. They felt balsam poplarwas the pioneer species on this ecosite and that succession would be to white spruce. The high tree cover limits the lightreaching the forest floor. Consequently, there is little forage available for domestic livestock. This community shouldbe rated as non-use.

G1: Aw/Bearberry/Rough fescue(Populus tremuloides/Arctostaphylos uva-ursi/Festuca scabrella)

n=8 This community type occupies dry, upper slope and hilltop positions and represents the invasion of aspenonto a Rough fescue-Sedge/Bearberry-dominated community type. The soils on this community type are fairly welldeveloped and the moisture conditions are high enough to favour the growth of aspen. In years of drought aspenwill likely die back in this community type. Frequent fire also tends to control the spread of aspen onto these roughfescue dominated grasslands. The lack of fire in the last 50 years has allowed many of these grasslands to beinvaded by aspen. Invasion of aspen causes a 50% decline in forage productivity and a loss in soil productivity.

G2: Aw/Rose/Hairy wildrye(Populus tremuloides/Rosa acicularis/Elymus innovatus)

n=5 This community type occurs on submesic, well drained, south and west-facing slopes. It is situated in slightlylower slope positions and therefore has better developed soils than the limber pine and bearberry-dominated communitytypes previously described. Archibald et al. (1996) described this community type as being part of the Canadabuffaloberry-hairy wildrye ecosite. They felt this ecosite to be relatively dry for the subregion, but not as dry as thelimber pine and bearberry ecosites. Succession on this site will likely be to the Pl/Buffaloberry/Pinegrass or Fd/Hairywildrye-dominated community types previously described. This community type has a moderate amount of forage fordomestic livestock. It should be rated as secondary range.

G3: Aw/Hairy wildrye(Populus tremuloides/Elymus innovatus)

n=1 This community type occurs on submesic, well drained, south and west-facing slopes within the Ya HaTinda area. It occurs in areas of the grasslands where moisture is sufficient to grow trees. Beckingham et al. (1996)described this community type as being part of the hairy wildrye ecosite. They felt this ecosite to be relatively dryfor the subregion, but not as dry as the bearberry and grassland ecosites. Succession on this site will likely be to thePl/Hairy wildrye or Sw/Hairy wildrye-dominated community types previously described. This community type hasa high amount of forage because of the increased moisture. In the winter elk often occupy these sites as beddingareas during the day. The southerly and westerly aspect increases solar gains and the trees provide a degree ofsecurity.

G4: Aw/White meadowsweet/Pinegrass(Populus tremuloides/Spiraea betulifolia/Calamagrostis rubescens)

n=16 This community is one of several community types which represent the mesic/medium ecosite for theMontane subregion. These sites can be dominated by Douglas fir, white spruce, aspen or lodgepole pine. Theunderstory can be dominated by white meadowsweet, pinegrass or feather moss depending upon the successionalstatus of the stand. In the vicinity of the Crowsnest Pass creeping mahonia is also common on these sites (Archibaldet al. 1996). White meadowsweet is well adapted to growing on dry rocky slopes (MacKinnon et al. 1992). Thepresence of a high cover of white meadowsweet may indicate slightly drier conditions and shallower soils than acommunity dominated by pinegrass. Because this community type is in an early successional stage it produces amoderate amount of forage for domestic livestock and should be considered secondary range.

This community is also very similar to the previouslydescribed Aw/White meadowsweet/Pinegrass community type, but the high cover of pinegrass and low cover ofwhite meadowsweet may indicate slightly moister, better developed soils. Pinegrass is generally unpalatable tolivestock, but if it is grazed early in the spring they will utilize it as a forage source. The forage productivity ofthis community type is moderate. As a result, this community should be rated as secondary range.

G6: Aw/Pinegrass-Kentucky bluegrass(Populus tremuloides/Calamagrostis rubescens-Poa pratensis)

n=7 This community type is very similar to the previously described Aw/Rose/Pinegrass community, but hasbeen grazed by livestock. It appears that this community type was grazed heavily in the past and then rested. Willoughby (1995) found that aspen stands that have been heavily grazed for prolonged periods have a low coverof native shrubs, forbs and grass species and a high cover of Kentucky bluegrass, clover and dandelion. Thiscommunity has a high cover of Kentucky bluegrass, but it also has a high cover of native shrubs, forbs and grass,which may indicate that it has been grazed heavily to the point of Kentucky bluegrass invasion and then restedallowing recovery of the native species. This community is very productive for domestic livestock, but Kentuckybluegrass provides a poor source of forage for wintering wildlife.

G7: Aw/Timothy-Kentucky bluegrass(Populus tremuloides/Phleum pratense-Poa pratensis)

n=13 This community is similar to the Aw/Rose/Pinegrass community, but heavy grazing pressure has shiftedthe understory away from native species and allowed dandelion, clover, timothy and Kentucky bluegrass toestablish on the site. This change in species composition with increased grazing pressure is similar to work doneby Willoughby (1995). The invasion of non-native species onto this site makes this community very productivefor domestic livestock, but the presence of overgrazed communities indicates some type of distribution problemand the management of the disposition should be discussed with the permittees.

These sites can be dominated by white spruce, aspen or lodgepole pine. The understorycan be dominated by thimbleberry, snowberry, saskatoon or pinegrass. Succession of this community type will likelybe to white spruce. The Aw/Thimbleberry dominated community type is probably moister and slightly richer than thiscommunity type.

G9: Aw/Snowberry/Kentucky bluegrass(Populus tremuloides/Symphoricarpos albus/Poa pratensis)

n=2 This community type is very similar to the previously described Aw/Snowberry-Saskatoon community,but has been grazed by livestock. It appears that this community type was grazed heavily in the past and thenrested. Willoughby (1995) found that aspen stands that have been heavily grazed for prolonged periods have a lowcover of native shrubs, forbs and grass species and a high cover of Kentucky bluegrass, clover and dandelion. Thiscommunity has a high cover of Kentucky bluegrass, but it also has a high cover of native shrubs, forbs and grass,which may indicate that it has been grazed heavily to the point of Kentucky bluegrass invasion and then restedallowing recovery of the native species. This community is very productive for domestic livestock, but Kentuckybluegrass provides a poor source of forage for wintering wildlife.

G9a: Aw-Pb/Marsh reedgrass(Populus tremuloides-P.balsamifera/Calamagrostis canadensis)

n=8 This community type was described on lower slope positions where some nutrient rich seepage occursduring the growing season. It is generally found north of the Porcupine Hills in areas that have north and easterlyaspects. Marsh reedgrass is not common in the Montane subregion and the presence of this grass species mayindicate that the climate is closer to the Lower Foothills or Subalpine subregion. This community type has a lowshrub cover and extensive cover of grass which makes it fairly attractive to livestock. Often these community typesare heavily utilized.

G10: Aw/Thimbleberry(Populus tremuloides/Rubus parviflorus)

n=8 Nutrient rich seepage occurs at some point in the growing season in this community type favouring thegrowth of thimbleberry. On these sites thimbleberry is very common south of the Crowsnest Pass and is generallyreplaced by cow parsnip north of the Pass. Succession on these sites will be from aspen to pine and then to whitespruce. Forage productivity on these sites is generally quite high because of the favourable moisture and nutrientconditions. Thimbleberry is generally unpalatable to livestock, but if the site has an abundance of cow parsnip itmay be extensively utilized. This community type should be rated as secondary range.

Both water birch and smooth willow are well adapted to growing adjacent to streams and ponds.What is unusual about this community is the high aspen and pinegrass cover. Aspen and pinegrass are usuallyassociated with more mesic sites. The high cover of willow, water birch and aspen limit the light reaching the forestfloor. Therefore there is only moderate production for domestic livestock. This community should be rated as non-use.

MONTANE CUTBLOCKS

In order to classify the cutblocks of the Montane subregion properly and understand thesuccessional sequences which occur after harvesting the preharvest community type and year thestand was harvested must be determined. This information was not available for thisclassification and therefore it was difficult to determine the successional pathways. For examplemany cutblocks in the Castle area and Porcupine Hills are not regenerating trees. It is not clear ifthese sites will always have difficulty growing trees because they were historically grasslands orif some other disturbance factor is influencing tree regeneration. Heavy grazing and competitionfrom grass species can influence tree regeneration, heavy grazing pressure was described on anumber of cutblocks in the Castle area. These cutblocks had been grazed so heavily that theagronomic species (Kentucky bluegrass, timothy and clover) dominated the sites and a numberof sites had been seeded with creeping red fescue which can compete with tree seedlings formoisture and nutrients.

Cutblocks can be an important source of forage for domestic livestock. They produce onaverage twice as much as deciduous stands and nearly three times more than conifer stands. Thisproduction varies from area to area in the Montane. Generally the production averages 1800 to1900 kg/ha in the Castle and Porcupine Hills and drops dramatically in the Gap area to 700kg/ha. It must be remembered that this increase in forage is only temporary. As the cutblockundergoes succession there will be a corresponding drop in forage production. Increases incarrying capacity after harvesting can be acquired through a temporary permit.

In order to understand the forage productivity on cutblocks between different areas ofthe Montane the cutblocks were split into the Gap, Castle and Porcupine Hills. It must beremembered that maximum forage productivity does not occur on a cutblock until it isapproximately 3 years old. One year old cutblocks will generally have less than half the totalproduction of a 3 year old block.

H4: Creeping red fescue (Castle)(Festuca rubra)

n=7 This community type represents cutblocks that have been heavily grazed and seeded with creeping redfescue. Creeping red fescue a rhizomatous grass can quickly form a sod on the top of the soil, which makes itdifficult to grow trees. These seeded cutblocks can be very productive for domestic livestock, but it will be verydifficult to regenerate trees on these sites.

Cypress Hills ecodistrict

The Cypress Hills ecodistrict is an unglaciated plateau ranging in elevation from about1300 m in the east to1465 m at the highest point. Once considered boreal foothills, the area hasbeen reclassified as montane given the bimodal summer precipitation peaks (June andSeptember), the potential for freezing temperatures in all months and the combination of closed-canopied lodgepole pine forest with fescue grassland (Strong and Leggatt 1992). Soil parentmaterials are somewhat unique on the plateau where ancient tertiary gravels are exposed, or, maybe capped by a variable veneer of loess; fine silty material deposited by wind from post glaciallake beds to the west of the plateau. Soils are mostly Black Chernozems where grasslandvegetation has dominated. Thelma soils are loamy Orthic Black Chernozems associated withrough fescue communities on the top of the bench. Also associated with rough fescue cover,Delmas and Marmaduke soil series are gravel and shallow to gravel Orthic Dark BrownChernozems found on the shoulder of the escarpment. Orthic Dark Grey Luvisols, like the soilsseries Reesor (loamy) have developed where lodgepole pine or aspen forest have prevailed(Greenlee 1981).

Plant communities described in the Cypress Hills are associated with the nearly levelplateau or the upper edges of the steep escarpment or rolling uplands. They include a mixture ofrough fescue grassland and closed canopy aspen and lodgepole pine dominated forests. TheRough fescue (Festuca campestris Rydb.) related plant communities of the Cypress Hills Plateauare unique in the relatively high canopy of Shrubby Cinquefoil (compared to fescue communitiesdescribed in southwestern Alberta and appears to be a function of the gravelly soil) and theabundance of Intermediate oat grass, a major subdominant grassland species (Moss 1955). Onthe steep, dry slopes Western Porcupine grass often replaces Intermediate oatgrass in thesegrassland communities. Idaho fescue also replaces Intermediate oatgrass on shallower soils withgentler slopes. An unresolved issue is the apparent expression of Rough fescue as the FoothillsRough fescue (F. campestris Rydb.) bunch grass type on the top of the plateau and the PlainsRough fescue (F. hallii Vassey) rhizomatous form on the adjoining slopes of the Cypress Hills.

I1. Foothills Rough Fescue - Western Porcupine Grass(Festuca campestris - Stipa curtiseta) Shrub Herbaceous

n=10 This is the reference plant community for thin break and gravel range sites in the upper slopes of theCypress Hills. There remains some uncertainty about the species of rough fescue found from the upper slopes ofthe Cypress Hills, down slope to the lower slopes of the mixed grassed. On the Cypress Hills bench, rough fescueexpresses as a bunch grass and then as a sod forming species as you progress downslope. Genetic studies proposedby Agriculture Canada may clear up this point of confusion in the future. Coupland (1961) described this plantcommunity and our analysis suggests that it is found on the drier thin break and gravel influenced sitesadjoining the Cypress Hills plateau and upper slopes. This community is very similar to the MGA1 community inthe adjoining mixed grass natural subregion. Subdominant species in this community more closely resemble theshrubby cinquefoil/rough fescue-Intermediate oatagrass community of the plateau, while the MGA1 more closelyresembles the adjoining dry mixed grass prairie. Mid-summer aridity is a common feature of these rangeland soilsgiven their exposure and coarse texture. Conservative stocking rates are needed to require adequate litter.Productivity data is presented from the Blue Field rangeland reference area.Soil Exposure: 6 % (0-17) Moss/Lichen Cover: 3 % (0-11) Total Vegetation: 84 % (67-95)

I 2. Shrubby Cinquefoil/Foothills Rough Fescue - Intermediate Oat Grass (Potentilla fruticosa/Festuca campestris - Danthonia intermedia) Shrub Herbaceous

n=37 This is the reference plant community for loamy and shallow-to-gravel range sites on top of the CypressHills plateau at about 1400 m elevation, and is associated with Thelma (THA) soils, orthic black chernozemsdeveloped on loess deposits over tertiary gravels. Rough fescue expresses itself as the F. campestris, bunch grasstype on the plateau while it appears as F. hallii, the rhizomatous type on the upper breaks and slopes of the plateau. This plant community has been described by Moss (1955) and Coupland (1961) who noted intermediate oatgrassas key subdominant species to rough fescue on the Cypress Hills plateau, vs. Parry’s oatgrass in montanegrasslands of southwestern Alberta (Willoughby et al 2001). Shrubby cinquefoil contributes a much higher canopycover in this community type at a mean cover of 14% versus about 3% in the foothills Montane communitydescribed by Willoughby et al 2001. Shrubby cinquefoil, intermediate oatgrass, Idaho fescue and a number of forbspecies will increase with grazing pressure. With control of wildfires, this community appears to be vulnerableto conifer encroachment, especially lodgepole pine. Like foothill rough fescue communities, this community tendsto have low soil exposure and a low cover of moss and lichen. The community is highly productive and in theabsence of grazing or fire will produce a very heavy litter build up. In the absence of grazing rough fescue willgrow to the exclusion of other species (Moss and Campbell 1947).Soil Exposure: 0(0-1) Moss/Lichen Cover: 3 % (0-98) Total Vegetation: 90 % (4-98)

n=17 This is a mid to late seral plant community on loamy and shallow-to-gravel range sites on the top of theCypress Hills plateau, and is associated with orthic black chernozems (Thelma) and orthic dark browns(Marmaduke). This plant community has a mixed structure of lightly grazed and heavily grazed patches thatresults in many fescue grasslands as a result of light stocking and summer grazing use. Cattle will graze roughfescue more uniformly under winter grazing use but under summer grazing will often choose other associatedspecies first (Willms and Rode 1997). More heavily grazed micro patches will be dominated by intermediateoatgrass and forbs and taller and more rank cover will be dominated by shrubby cinquefoil and rough fescue.

I4. Shrubby Cinquefoil / Foothills Rough Fescue - Idaho Fescue (Potentilla fruticosa / Festuca campestris - Festuca idahoensis) Herbaceous Shrub

n=6 This is a reference plant community for shallow-to-gravel range sites on the Cypress Hills Plateau. Though the shrubby cinquefoil/foothills rough fescue - intermediate oatgrass community type is most common on theplateau, this community type occurs on similar soils but with thinner loess deposits over gravels (Thelma andMarmaduke). This community type tends to have a lower canopy cover of shrubby cinquefoil and a greater groundcover of moss/lichen compared to I2. With grazing pressure, Idaho fescue and forb cover will increasesignificantly.

I5. Buckbrush / Kentucky Bluegrass - Timothy (Symphoricarpos / Poa pratensis - Phleum pratense) Shrub Herbaceous

n=3 This is a modified plant community where disturbance history has resulted in the replacement of nativespecies by invasive agronomic species and weeds. This plant community may provide reasonable forageproduction during wet years but will produce little forage in average moisture to dry years. Forage quality declinesrapidly as forages mature and the community has little value for dormant season grazing. Based on currentknowledge, there seems to be little potential for this community to recover to a native stand. Grazing managementshould aim to promote vigor and productivity of Timothy and Brome grass to reduce the relative cover ofKentucky bluegrass and provide more competition to weed species like Canada thistle.Soil Exposure: 0 % (0-0) Moss/Lichen Cover: 0 % (0-0) Total Vegetation: 98 % (98-98)

I6. Silverberry / Kentucky Bluegrass (Elaeagnus commutata / Poa pratensis) Shrub Herbaceous

n=1 The silverberry dominated plant communities occur on alluvial floodplain terraces, in V-shaped ravinesand swale-like depressions where overland flows provide additional moisture (Thompson and Hansen 2002).Where silverberry is very dense forage production is very low, however in more open stands livestock use can beextensive which leads to the invasion of Kentucky bluegrass, Timothy and dandelion. In the absence ofdisturbance silverberry dominated communities can undergo succession to aspen or balsam poplar and then whitespruce.

I7. Pl-Aw/Bunchberry/Moss(Pinus contorta-Populus tremuloides/Cornus canadensis/Pleurozium schreberi)

n=18 This community is found on northerly aspects, which probably escaped fire and disturbance, allowingsuccession to occur. Continued succession in the absence of disturbance will likely be to the Sw/Moss dominatedcommunity type. This community type is moderately productive for domestic livestock. The higher moistureconditions favour the growth of fireweed and aster spp. These species are moderately palatable to livestock. Thiscommunity type would be rated as secondary range for domestic livestock.
